Rabbit jumping crazily in cage

This might be due to shock, but you can try to transfer it to a quiet place in time, and gradually calm it down through feeding snacks and other measures. During this period, avoid touching it again and reduce the noise in the surrounding environment. If there is no improvement after changing the location, it's better to take it to a pet hospital for inspection to see if it's caused by some diseases.

Rabbit suddenly jumping crazily in cage

There could be several reasons for a rabbit to suddenly start jumping crazily in its cage:

The rabbit might be hungry or thirsty, and jumping crazily to ask for food and water. It's advised to feed the rabbit on a regular schedule.
The rabbit might be in heat, which can cause it to act randomly in its cage.
The rabbit might be sick or infected with a pathogen, causing it to feel uncomfortable and jump crazily. It's recommended to check for any other clinical symptoms and treat promptly.

Rabbit's behavior after being scared

The rabbit's heart rate accelerates, breaths heavily, runs around frantically, becomes depressed, and hides in corners. Rabbits are timid animals, and even a loud noise or another animal can cause them to be scared, or even die from fright. It's best to provide a quiet environment for rabbits, and avoid taking them on trips, as stress reactions can lead to death.

What to do after a rabbit is scared

When a rabbit is scared, it may experience incontinence and even pseudo-death. So, it's important to change the rabbit's environment promptly after it's scared, and transfer it to a quiet and dark place. At the same time, give it some food to slowly alleviate its discomfort. Also, reduce the visits of strangers or touching during this time. Once the rabbit stabilizes, you can put it back in its original living place.
